PCA9538 Datasheet (NXP) - 8-bit I2C and SMBus low power I/O port

PCA9538, 8-bit I2C and SMBus low power I/O port

The PCA9538 is a 16-pin CMOS device that provide 8 bits of General Purpose parallel Input/Output (GPIO) expansion with interrupt and reset for I2C/SMBus applications and was developed to enhance the Philips family of I2C I/O expanders.

I/O expanders provides a simple solution when additional I/O is
